Guide for Power Connectors
|
|
The purpose of this guide is to serve as a reference for utilities with regard to definition and basic characteristics of electrical bolted connections, material composition, installation, design manufacture, standardization, inspection and testing of power connectors. This guide provides a clear and uniform procedure for assembling busbar connections.
Power connecions are generally the weak links in electrical transmission and distribution systems. Overheating of connections in both overhead and underground systems, often due to poor installation practices, are probably the most frequent sources of detriment to the overall performance of a power system. Accurate knowledge of the sources affecting these can lead to substantial improvement in the network reliability within the allowable operating limits. To achieve these objectives engineers and technical personnel must understand the basic principles of power connections and practical insights into degradation and failure mechanisms.
To address these issues of concern, this guide describes the basic principles of electrical contacts and includes recent advances in the understanding of processes associated with the operation of power connections. Emphasis is placed on the physical causes for performance attributes and limitations of power conenctors. The use of effective mitigating measures for slowing connector degradation and restoring the original capability of connectors to satisfy system requirements is discussed and illustrated. Opportunities for connector life extension are also addressed.
